this is a strip of paper where down is later. the amber line is NOW — it sweeps down the page, filing what you wrote into the dimmed past above it. nothing locks: log it, backfill it, replan it — the whole strip is yours, both directions.
no account, no cloud — your notes live in this browser only. ⇩ export is the backup: one JSON file, yours to keep.
the ink is dry — this is history. tearing it out destroys the words forever; a tombstone keeps the time slot so no old backup can bring them back. if you only want it hidden, redact it instead.
